Tardive and Withdrawal Dyskinesia Associated with Haloperidol

Abstract

Four cases of dyskinesia attributable to treatment with 4-20 mg. of haloperidol daily for more than a year are reported. Two cases involved temporary oral-facial dyskinesias and the others a more persistent complex mixture of neurological features. The possibility that tardive dyskinesia may be associated with the butyrophenones in addition to other antipsychotic agents should be considered, the authors believe.
